Quote1 Maybe if we share a piece of ourselves, we can break out of our old cycles of violence and pain. Create a new world for you, Nora. A better one. One where we can coexist. All of us. Together. A world where nothing has to be impossible... As long as we believe in it. Quote2

  • This episode is the series finale of The Flash as well as the last episode to be set on the Arrowverse main Earth.
    • The subtitle of the episode, which is not part of the episode name, is "Finale".
  • Jay Garrick mentions having met Earth-90 Flash in the Post-Crisis Multiverse. This implies that the continuity of Earth-90, which was erased in "Elseworlds, Part 1", and the existence of Barry Allen, who died in "Crisis on Infinite Earths: Part Three", were restored in the aftermath of the rebirth of the Multiverse.
    • As other realities' continuities were also reverted back to the events of the respective TV shows/movies in the Post-Crisis Multiverse,[1] the continuity of Earth-90 probably shares a similar fate.
  • The Legion of Zoom members are displaced from important moments in their histories:
    • Zoom is displaced just before the Time Wraiths turned him into the Black Flash and dragged him into the Speed Force from "The Race of His Life";
    • Godspeed is displaced just before he tried to murder Bart West-Allen in "Heart of the Matter, Part 1";
    • Savitar is extracted before being erased from the timeline in "Finish Line";
    • Thawne is extracted before his ultimate death in "Negative, Part Two".
  • Max Mercury becoming an avatar of the Speed Force was originally glimpsed by Barry Allen in "Into the Still Force". This episode closes his temporal paradox as Barry always knew he had to gift him his Speed Force powers.
